Replying to Lightroom tech help

Has anybody ran into the issue of Lightroom operating in low quality? I'm running the latest Lightroom on my PC with a 4K screen. However, Lightroom is operating as if the screen is 1536x864. It also thinks I have Windows 8, when in fact I have Windows 10.

If I google this all I get are how to change resolution specs when exporting photos. I can't find anything on changing the display resolution of Lightroom itself.

I completely uninstalled Lightroom yesterday and then reinstalled, but it still doesn't display properly.

Hoping there's someone out there who knows a fix!!
